My range is a bmw 118d, has gone from less than 950 km to more than 1050 km, for "country" trips ... a good 5% to 10% fuel savings ...
At 100km I go from 5.4L / 100km to 5.0 L / 100km according to the on-board computer.
The car is more "lively" and "seems" lighter but that does not make it dangerous for all that, it just makes less "rail" must be adapted (me who drove in twingo for years that does not bother me too much) ... on the other hand, the speed regulator no longer works since the failure ... surely a security.
An estimate of autonomy by the computer:
Another clue that we know how to make engines sober but full of "gadgets" (more or less useful ... ok it's useful, it's active safety ...) but which make consumption seize up. ..
Technically, the DTC / DSC must constantly play on the braking, in the end I still gain wear on the pads and discs

Dynamic Stability Control (DSC).
Dynamic Stability Control (DSC) makes it easier to control the vehicle, even in adverse conditions or on difficult surfaces, and thus increases active safety.
Dynamic Stability Control (DSC) oversees all driver assistance systems in BMW vehicles. It optimizes trajectory holding in all circumstances as well as traction during start-up or acceleration. It also detects conditions of instability such as understeer or oversteer and helps the driver to restore the vehicle to its path.
Ultra-sensitive sensors constantly detect the operating conditions in progress. This information is delivered by sensors of wheel rotation speed, steering degree, lateral acceleration, pressure and yaw rate (vehicle rotation around its vertical axis). The simulation module defined for a stable vehicle condition in the DSC control module serves as a basis for comparison with respect to the degree of steering actually applied to the steering wheel by the driver and the speed of the vehicle.
In the event of a discrepancy between the calculated setpoints and the actual measured values outside the tolerance ranges, the system takes the necessary actions to stabilize the vehicle or correct the traction. To this end, the system requests engine management, braking system management and the xDrive system if it is an all-wheel drive vehicle.
The system can restore the vehicle's stability or translate a traction demand by the driver by a reduction or suspension (with a regulator of the engine inertia torque) of the engine torque as well as by a targeted application of the brakes on one or more wheels.
In combination with Active Steering, the yaw rate regulation integrated into the system can significantly reduce the steering effort at the steering wheel of the driver and the intensity of the DSC corrective intervention.

Dynamic Traction Control (DTC).
Dynamic Traction Control (DTC) enables sporty and dynamic driving, even when the DSC trajectory corrector is active, to provide increased traction.
Dynamic Traction Control (DTC) is a switchable sub-function of Dynamic Stability Control (DSC). The DTC basically acts in two application spectra, namely satisfying an increased traction demand or authorizing a sporty driving when the DSC is operating.
When the front wheels are braked by the resistance of a mass of melted snow or a large thickness of snow for example, there is an apparent slip at the rear axle (the rear wheels turn faster than the wheels before, thereby establishing a power overrun criterion) which triggers the regulating intervention of the DSC motor torque. In this kind of situation, such an action would generally have the effect of reducing the engine torque more than necessary. The entry into action of the DTC exerts a positive influence in this scenario by establishing the conditions for better traction without significant reduction in the driving force.
Activating the DTC significantly increases the driver's room for maneuver until the intervention of the DSC stabilizes the vehicle. Control of the vehicle remains a prerogative in its own right for the driver.
In short, the DTC / DSC can be disabled manually, I had never done it before ... It is most certainly disabled on other cars ...
Who has a traction control that can be easily deactivated and who wants to test, at least on a tank, to compare?
